Examples

IMUXsense

1. Uses data from the Kuopio Gait Dataset
2. Download MTI Manager and install. Use the extra steps for Linux if needed.
3. Load an .mtb file representing a trial into MTI manager.
4. Export from MTI Manager using the following settings

Minimal Bug Reproduction

Triangle Inequality

For reproducing this error:

what(): SimTK Exception thrown at MassProperties.h:542: Error detected by Simbody method Inertia::operator-=(): Diagonals of an Inertia matrix must satisfy the triangle inequality; got 0.000105365,0.00021073,0.00105365. (Required condition 'Ixx+Iyy+Slop>=Izz && Ixx+Izz+Slop>=Iyy && Iyy+Izz+Slop>=Ixx' was not met.)

use IMUIKTriangleInequality example and build opensim-core. Tested with and without python or java bindings and it didn't make a difference

Locale IO Problem

For reproducing this error:

what(): Timestamp at row 0 with value 0,000000 is greater-than/equal to timestamp at row 1 with value 0,000000 Thrown at TimeSeriesTable.h:533 in validateRow().

use the IMUIKLocaleProblem example

Build Instructions

1. Make sure you have opensim-core installed and on path

2. Change to example project directory

cmake -B build .

cd build
make
